Update on bariatric surgery in adolescence

Recent evidence highlighting the prevalence of severe obesity in the pediatric population, coupled with disappointing outcomes related to medical weight loss interventions, has led to increased interest in bariatric surgery. This article focuses on recent additions to the literature regarding the current indications and outcomes of adolescent bariatric surgery, emerging guidelines on the development of surgical weight loss programs and the status of access to bariatric surgical care for adolescents in the United States. Current data have shown a steady rise in the use of bariatric surgery among adolescents and serve to highlight the prevalence of several important obesity-related comorbidities. In addition to reports showing the safety and efficacy of adolescent bariatric surgery, a number of investigators have demonstrated significant improvement in key physiological and metabolic parameters (i.e., glucose metabolism, elevated blood pressure, dyslipidemia, etc.), offering updated consensus-driven guidelines for the indications for surgical intervention, as well as the development of multidisciplinary adolescent-specific care. Despite favorable outcomes, a disparity exists between the pediatric and adult populations related to access to such care. In contrast to previous small and mostly retrospective series, contemporary studies have shown that adolescent bariatric surgery is well tolerated and effective. Despite these findings and the emergence of a national consensus regarding multidisciplinary care, skepticism among primary care providers, as well as significant challenges related to healthcare access, remain. Longitudinal studies and open dialogue within the medical community are needed

Alveolar capillary dysplasia: A logical approach to a fatal disease

Purpose: The aim of the study was to review the authors' experience with alveolar capillary dysplasia (ACD), a cause of persistent pulmonary hypertension of the neonate (PPHN) caused by decreased alveolar units, dilated anomalous pulmonary veins, thick-walled arterioles, and thickened interalveolar septa. Methods: The records of all neonates with ACD were reviewed from Children's Hospital, Columbus, Ohio, and Sophia's Children's Hospital, Rotterdam, The Netherlands. The clinical characteristics and pathological findings are discussed. Results: Eight neonates were diagnosed with ACD from 1994 to 2002. Twenty-five percent (2/8) experienced respiratory distress immediately after birth, whereas 75% (6/8) had normal Apgar scores but deteriorated 1.5 hours to 30 days after birth. All infants required conventional ventilation initially; 50% (4/8) were placed on high-frequency oscillating ventilation and 87% (7/8) on extracorporeal membrane oxygenation. A premorbid diagnosis was established in 3 patients by open lung biopsy. The diagnosis of ACD was confirmed at autopsy in all patients. Conclusions: ACD is a fatal disease that should be suspected in all neonates with respiratory failure and PPHN who fail conventional therapy. Prompt diagnosis helps to avoid prolongation of costly treatment modalities in a uniformly fatal disease. An algorithm is proposed in which neonates with PPHN who fail treatment with extracorporeal membrane oxygenation are managed by open lung biopsy

Simultaneous Robotic-Assisted Laparoscopy for Bladder and Bowel Reconstruction

© Copyright 2018, Mary Ann Liebert, Inc., publishers 2018. Introduction: Patients with neurogenic bladder frequently also have bowel dysfunction and a simultaneous urologic and colorectal reconstruction is possible. We present our experience with combined reconstructive procedures using robot-Assisted laparoscopy, and demonstrate the utility of a minimally invasive approach that considers both the bowel and bladder management of these patients. Methods: We retrospectively reviewed all patients who underwent combined bowel and urologic reconstruction at our institution since the start of our multidisciplinary robotic program. Results: Seven patients were identified in our cohort with a mean age of 6.4 years (3.8-10.1 years). Six patients had myelomeningocele and 1 had caudal regression. Malone appendicostomies were placed in all 7 patients. A split appendix technique was used as a conduit in 5 patients, in situ appendix in 1, and neoappendicostomy with cecal flap in 1. Six patients had a Mitrofanoff appendiceal conduit created, while 1 patient had a sigmoid colovesicostomy for urinary diversion. Five patients required bladder neck repair. One patient had stenosis of the Mitrofanoff and one patient had an anastomotic leak of the sigmoid anastomosis. The average operating time was 526 minutes (313-724 minutes). The median length of stay (LOS) was 5 days (4-7 days), excluding one outlier who suffered an anastomotic leak and had an extended LOS (50 days). All patients who underwent continent bladder reconstruction are dry on their current catheterizing regimen, 6/7 are clean with antegrade flushes. Conclusion: Patients with neurogenic bladder often have coexisting bowel dysfunction, which provides an opportunity to reconstruct both organ systems simultaneously and achieve social urinary and bowel continence. Before committing to any intervention, the surgeon should consider both the urologic and gastrointestinal needs of the patient, and perform the needed procedures simultaneously. We describe a number of combined operations aimed at bowel and bladder management that can be performed safely using robot-Assisted laparoscopy

Changes in weight and co-morbidities among adolescents undergoing bariatric surgery: 1-year results from the Bariatric Outcomes Longitudinal Database

Bariatric surgery is 1 of the few effective treatments of morbid obesity. However, the weight loss and other health-related outcomes for this procedure in large, diverse adolescent patient populations have not been well characterized. Our objective was to analyze the prospective Bariatric Outcomes Longitudinal Database (BOLD) to determine the weight loss and health related outcomes in adolescents. The BOLD data are collected from 423 surgeons at 360 facilities in the United States. The main outcome measures included the anthropometric and co-morbidity status at baseline (n = 890) and at 3 (n = 786), 6 (n = 541), and 12 (n = 259) months after surgery. Adolescents (75% female; 68% non-Hispanic white, 14% Hispanic, 11% non-Hispanic black, and 6% other) aged 11 to 19 years were included in the present analyses. The overall 1-year mean weight loss for those who underwent gastric bypass surgery was more than twice that of those who underwent adjustable gastric band surgery (48.6 versus 20 kg, P < .001). Similar results were found for all other anthropometric changes and comparisons within 1 year between surgery types (P < .001). In general, the gastric bypass patients reported more improvement than the adjustable gastric band patients in co-morbidities at 1 year after surgery. A total of 45 readmissions occurred among gastric bypass patients and 10 among adjustable gastric band patients, with 29 and 8 reoperations required, respectively. The weight loss at 3, 6, and 12 months after surgery is approximately double in adolescent males and females who underwent gastric bypass surgery versus those who underwent adjustable gastric band surgery. Bariatric surgery can safely and substantially reduce weight and related co-morbidities in morbidly obese adolescents for ≥1 year
